Scrap Wood Pencil Cups

I needed to use up some scrap wood and in the spirit of back-to-school made some pencil cups for the Makerspace. This is a method for making a vessel without lathe; just two hole saws, a power drill and our spindle sander. The process is quite versatile too. Sized up these could be made as flower pots, shallower they could be trinket dishes, and so on.

Dewalt 20v MAX XR Hammer Drill
Hole Saws: 4.5″ Spyder and 3.625″ Spyder (these come in a wide range of sizes, get what is right for what you need)
Wen Spindle Sander

Once I had the largest of the two hole saws locked into place on my drill, I set up two pieces of scrap wood to drill on top of, and clamped my first piece on top so it was secure. I did this so I wouldn’t drill into the table. From there I drilled a wide range of circles in the same size from pieces of my scrap wood. I wanted a mix of wood types and thicknesses to add visual interest.

I’ve found that the key to getting good results with a hole saw is applying moderate pressure and keeping a steady hand. The hole saw can heat up when used on thicker pieces, so be ready. The slower you go, the less scorching you can expect. 

Once I had a good mix of round disks, I made different arrangements of them until I was happy with it. All of the scrap wood circles should have a hole directly in the center from the hole saw which will line up perfectly when they are stacked.

To prep for the glue, I lined my pieces up in the order I wanted them. I painted the top of the bottom piece with a liberal coat of wood glue. Then, using a drill bit as a guide for the holes on the circles, I stacked the next piece on top. I repeated this process until I had the whole stack assembled. I used TitebondIII Woodglue because it was what I had on hand but most wood glues would work well for this. I pushed the drill bit all the way in to keep it aligned while I clamped the block. Once I had it clamped down, I removed the drill bit and cleaned it off so it didn’t glue itself in place.

This dried overnight. I used two parallel bar clamps and plywood to clamp the piece down to my table. I also added a piece of plywood as a bumper to create resistance when I drill in with the smaller hole saw.

This would be easier on a drill press, but I will try and be as level as possible as I’m going in with my drill. Also, the hole down the middle of this will help guide the hole saw as I go. The main reason that I chose to go with the drill to show a method that doesn’t require big expensive tools.

On the first side, I went as far as I could until I bottomed out the hole saw. Then I flipped my piece. In theory, as long as I lined up with that hole I drilled on the other side, I could expect it to work perfectly. 

And it did!

The core ended up big enough to make a second pencil cup, so I repeated the process on that one with another smaller hole saw.

To sand these down, I used my spindle sander. I only sanded down the interiors at this point, starting at an 80 grit sandpaper to sand the bulk of the imperfections off quickly. Later I topped it off with a 220 grit to smooth things off and give a nice finish sand.

Using a wood glue and CA glue combination, I glued a disc to the base of each shell. The wood glue dries slowly for a strong bond, and the CA glue dries immediately when it comes into contact with activator and serves as a clamp.

I switched out the attachment on my spindle sander and sanded down the outer edge. I took my time, and sanded the cup vertically and horizontally. I made sure to keep spinning it around so I would get an even sand. I smoothed things out with a 220 grit at the end.

At this point I removed the excess dust with paint thinner and I let both cups dry completely. Then it was time for the finish! I finished these with 3 coats of satin wipe-on poly which gave it a nice high end look in my opinion.

This ended up being a really effective method to make a container without using a lathe.
